Answer:
The skeletal muscle is stimulated by means of action potentials that are caused by the neuromotor plate. These action potentials are one after the other and can become cumulative once the muscle fibers pass the refractory phase of the action potential.
The refractory stage is that stage in which action potentials are not admitted, therefore where the muscle fibers do not accept stimuli to contract.
Once this refractory stage is over, more action potentials can be admitted, which would be summative and the muscle fiber would contract with greater power.
Explanation:
If a muscle is repeatedly stimulated, the contraction will be weaker or the muscle will fatigue more easily, triggering muscle failure.
If the muscle is stimulated with a longer pause between contraction and contraction, the action will be performed with more power.
Answer:
This question lacks options, the options are:
A) The financial costs for the farmer would be lowered.
B) Federal agencies could initiate legal action against the farmer.
C) The farmer may be held responsible for increasing chemical pollution.
D) The farmer's expenses for pest control would increase due to an increase in bee population.
The answer is A.
Explanation:
Genetic engineering or modification is a process whereby the genome of an organism is manipulated in order to achieve a desirable trait in the organism. In this question, a farmer uses an approved genetically engineered corn plant, which produces pollen that can make its own toxins to repel pests.
Using this genetically modified corn plant means that the farmer no longer require the application of chemical pesticide to control the pests affecting his corn plant. The impact on the farmer of growing such a variety of corn is that the financial costs for the farmer would be lowered since he won't have to purchase chemical pesticides any longer.

nebular hypothesis
The most widely accepted theory of planetary formation, known as the nebular hypothesis, maintains that 4.6 billion years ago, the Solar System formed from the gravitational collapse of a giant molecular cloud which was light years across. Several stars, including the Sun, formed within the collapsing cloud.
Answer: both cells have structures in common. All cells have a plasma membrane, ribosomes, cytoplasm, and DNA.
